Closing the fuel filler door
1. To install the fuel tank cap, turn it
clockwise until it “clicks” one time.
2. Close the fuel filler door until it is
latched securely.
Information
To lock the fuel filler door, make sure the
fuel filler door is completely closed. Press
the LOCK button on the remote key or
smart key to lock your vehicle. The fuel
filler door will also lock.
Note that if the fuel filler door is not
completely closed when the vehicle is
locked, the fuel filler door will not be
locked.
CAUTION
Make sure the fuel filler door is
completely closed before driving
through a car wash or operating a high
pressure spray washer.
WARNING
Automotive fuel is highly flammable
and explosive. Failure to follow these
guidelines may result in SERIOUS
INJURY or DEATH:
• Read and follow all warnings posted
at the gas station.
• Before refueling, note the location
of the Emergency Fuel Shut-Off, if
available, at the gas station.
• Before touching the fuel nozzle, you
should eliminate the potential build-
up of static electricity by touching
a metal part of the vehicle, a safe
distance away from the fuel filler
neck, nozzle, or other gas source,
with your bare hand.
• Do not use mobile phones while
refueling. Electric current and/or
electronic interference from cellular
phones can potentially ignite fuel
vapors and cause a fire. •
Do not get back into a vehicle
once you have begun refueling.
You can generate a buildup of
static electricity by touching,
rubbing or sliding against any item
or fabric capable of producing
static electricity. Static electricity
discharge can ignite fuel vapors
causing a fire. If you must re-enter
the vehicle, you should once again
eliminate potentially dangerous
static electricity discharge by
touching a metal part of the vehicle,
away from the fuel filler neck, nozzle
or other fuel source, with your bare
hand.
• When using an approved portable
fuel container, be sure to place the
container on the ground prior to
refueling. Static electricity discharge
from the container can ignite fuel
vapors causing a fire.
Once refueling has begun, contact
between your bare hand and the
vehicle should be maintained until
the filling is complete.
• Use only approved portable plastic
fuel containers designed to carry and
store fuel.
• When refueling, always shift the
gear to the P (Park) position, set
the parking brake, and press the
Engine Start/Stop button to the
OFF position. Sparks produced by
electrical components related to the
engine can ignite fuel vapors causing
a fire.
• Do not use matches or a lighter and
do not smoke or leave a lit cigarette
in your vehicle while at a gas station,
especially during refueling.

How vehicle radio works
FM reception
OJF045308L
AM and FM radio signals are broadcast
from transmitter towers located around
your city. They are intercepted by the
radio antenna on your vehicle. This signal
is then received by the radio and sent to
your vehicle speakers.
When a strong radio signal has reached
your vehicle, the precise engineering
of your audio system ensures the best
possible quality reproduction. However,
in some cases the signal coming to your
vehicle may not be strong and clear.
This can be due to factors, such as
the distance from the radio station,
closeness of other strong radio stations
or the presence of buildings, bridges or
other large obstructions in the area.

05
5-141
Using a cellular phone or a twoway
radio
When a cellular phone is used inside
the vehicle, noise may be produced
from the audio system. This does not
mean that something is wrong with the
audio equipment. In such a case, use
the cellular phone at a place as far as
possible from the audio equipment.
NOTICE
When using a communication system
such as a cellular phone or a radio set
inside the vehicle, a separate external
antenna must be fitted. When a cellular
phone or a radio set is used with an
internal antenna alone, it may interfere
with the vehicle’s electrical system and
adversely affect safe operation of the
vehicle.
WARNING
Do not use a cellular phone while
driving. Stop at a safe location to use a
cellular phone.
